This application relates to the field of display technologies, and inparticular, to a display apparatus and a method for driving same.

Related Art

The attributes of liquid crystal cells of an active switch-liquidcrystal display (TFT-LCD) cannot be always fixed, and remain unchangedat a particular voltage. Otherwise, even if the voltage is eliminatedafter a long time, the liquid crystal cells cannot rotate due to thechange of the electric field to form different gray scales, because theattributes are destroyed. Therefore, the voltage needs to be recoveredback every other period of time, to prevent the attributes of the liquidcrystal cells from being destroyed.

Therefore, polarity inversion drive methods of different types have beendeveloped. For example, there is a frame inversion method. The method isto inverse, every other frame, the polarity of display data provided tothe liquid crystal cells. A column inversion method is to inverse thepolarity of display data every other given number of columns of pixels..Similarly, a row inversion method is to inverse the polarity of displaydata every other given number of rows of pixels. A dot inversion methodis to inverse the polarity of display data every other given number ofpixels.

However, each of the polarity inversion methods has an advantage overother inversion methods as well as an inevitable disadvantage. Forexample, the column inversion method has excellent performance onelimination of data delay of data lines and reduction of powerconsumption, but may cause a vertical flickering phenomenon, leading toreduction of the image quality. Although the frame inversion method ismost power-saving, the image quantity is poorest. The dot inversionmethod has optimal anti-flickering performance, but has highest powerconsumption. However, a same polarity control manner is used in alldisplay zones of the display panel at the present stage. Consequently,relatively good balance cannot be achieved among the image quality, theflickering phenomenon, and the operation power consumption.
